AxLEV-LVU BRICATOR,

SPECIFICATION forming part of Letters Patent No. 686,588, dated November 12, 1901. Application filed July 8, 1901. Serial No. 67,383. (No model.)

To @ZZ whom t may concern:

Be it known that I, ANDREW R. CARR, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in'Axle- Lnbricators, of which the following is a specication. Y Y

This invention relates to axle-lubricators, and particularly to that class of lubricators applied to the driving or truck axles of locomotives and which are provided with a stationary box or cellar packed with waste I or other suitable absorbent material satu rated with a liquid lubricant.

The object of the invention is to provide a lubricator of this character with an improved upwardly spring-.pressed trough which will always press the oil-saturated absorbent material against'the axle, and thereby continuously feed oil to the latter, and which trough can be readily mounted in a stationary box or cellar of the type now in use without changing the construction of said box.

The invention consists in certain constructions, arrangements, and combinations of the parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a longitudinal sectional side elevation of the improvement applied to the axle of a locomotive. Fig. 2 is a vertical transverse section thereof. Fig. 3 is a detail side elevation of the oil-trough. Fig. 4 is a detail plan view of the stationary box or cellar. Fig. 5 is a detail perspective view of one of the two upright posts that serve as supports for the springs and as guides for the oil-trough. Fig. 6 is a detail edge view of one of the two springs which together yieldingly support the oil-trough.

Referring to the drawings, the letter a designates a locomotive-axle adjusted in an axlebox b, which is provided with a brass crownbearing c, and d designates the stationary rectangular cellar of the axle-box, two opposite sides of said cellar being provided with semicircular'recessed upper edges d', which partially surround the axle, but are out of frictional4 contact with the same. To the inner wall of each of the other two sides of the said cellar d is rigidly secured by bolts e or the like an 'upright post f, one of which is shown in detail in Fig. 5. Said posts `are provided on their sides adjacent the cellarwall with horizontal slots g, which are closed by said cellar-walls, and an undulating or bow-shapedleaf-spring h is held intermedid ate ofvits ends in `each slot g, as shown best in Fig. 4, the two ends of each spring being free.

The letter t' designates the oiltrough, which is of substantially rectangular shape and is preferably stamped out of sheet-brass or other suitable thin metal. Said trough is intended to be received within the cellar d and is provided at two opposite sides with vertical recesses or guide-ways j, coincident with the two posts f, and is also provided on the same sides and intermediate of its top and bottom with horizontally-extending downwardly-facing shoulders or ledges lo, at each end of which is secured a hard metal wearplate Z, adapted to bear on the free ends of the springs h. Thus the said trough is supported to yield in a vertical direction and is guided in its vertical movements by the said posts f. The other two sides of the oil-trough t' have semicircular recessed upper edges i', which are outwardly flared, as shown in Figs. l and 3, and which partially surround and are in contact with the axle a.

The oil-trough t' is packed with waste or similar absorbent material m, which is saturated with oil. The said trough being pressed upwardly by the springs h will always be kept in contact with the axle a and will continuously feed oil to the same, even when the axle becomes worn by frictional engagement with the upper edges of the trough, and the outwardly-flared semicircular edges 1l of the trough serve as dust-guards and prevent dust and grit from entering the trough.

It is to be especially noted that my invention can be readily applied to the ordinary boxes or cellars in use at the present time, as it is only necessary to place the springs h in the slots g of the ports f, then bolt or rivet the said posts to opposite sides of the cellar d, and finally place the troughz' in the cellar.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an axle-box, a lubricator, comprising a cellar provided at opposite sides with ver- IOO tical posts; leaf-springs supported intermediate their ends by said posts with the ends of said springs free; and an oil-trough mounted in said cellar and provided at opposite sides with downwardly-facing ledges bearing on the ends of said springs. 1

2. In an axle-box, a lubricator, comprising a cellar provided at opposite sides with vertical posts; springs secured intermediate their ends to said posts; an oil-trough mounted in said cellar and provided at opposite sides with downwardly-facing ledges; and Wear-plates secured to the said ledges and bearing on said springs whereby to yieldingly support said trough.

3. In an axle-box, a lubricator, comprising a cellar provided at opposite sides with vertical posts in which are formed slots; bowshaped springs held intermediate their ends in said slots; and an oil-trough mounted in said cellar and provided intermediate its top and bottom with downward1yfacing ledges which bear upon the ends of said springs.

4. In an axle-box, a lubricator, comprising a cellar; two Vertical posts secured to opposite sides of said cellar; springs secured intermediate their ends to said posts; and an oil-trough mounted in said cellar and provided in its sides with vertical guideways coincident with said posts, and also provided with downwardly-facing ledges on each side of said guideways and Which bear upon said springs.

5. In an axle-box, a lubricator, comprising a cellar provided at opposite sides with vertical posts; bow-shaped springs held intermediate their ends on said posts; and an oil trough mounted in said cellar-and provided intermediate its top and bottom with horizontally-extending downwardly-facing ledges, 7c, bearing on the ends of said springs, as set forth.

In testimony whereof I affix my signature in the presence ot two witnesses.
